Question

I have following text after reading a file:

06/16/2011 04:01:05 AM : Process Start
06/16/2011 04:01:05 AM : Creating File
06/16/2011 04:01:05 AM : Opening File
06/16/2011 04:01:05 AM : Writing Text
06/16/2011 04:01:05 AM : Closing File
06/16/2011 04:01:05 AM : Sending File in email
06/16/2011 04:01:05 AM : Process End

I want to remove date and time in the beginning of each line like this:

Process Start
Creating File
Opening File
Writing Text
Closing File
Sending File in email
Process End

How can we do this with string matching technique ?

Thanks

Answer 1

One way to do this would be the following: (assuming the prefix is always the same length)

$output = '';
$tmp    = explode("\n",$input);

foreach($tmp as $t)
    $output .= substr($t,25)."\n";

echo $output;

First you explode the input into a variable by splitting it on every new line, and then for each line you remove the first 25 characters to create a new output.
